The fine-branchingstructures in high-pressure, low-density polyethylenes (HP-LDPEs) have
been studied by 50.10-MHz 13C NMR analysis. When the 13C NMR spectra of some HP …

Qualitative and quantitative analysis of short chain branches was carried out on a series of
low-density polyethylenes by Fourier transform infrared spectroscopy. The peak position of …

An optimized experimental procedure has been developed for the 13 C-NMR analysis of
polyethylenes. These analyses were performed at 62.5 MHz in 60–80 (w/w)% mixtures in …

During the preparation of poly (vinyl chloride)(PVC) under low monomer pressures,
intramolecular hydrogen transfers (“backbites”) lead to the formation of small amounts of 1, 3 …

Abstract Poly (oxy-1, 4-benzenediylcarbonyl)(POB) whiskers from p-acetoxybenzoic acid
were prepared in mixtures of liquid paraffin having many branched carbons (LP) and …

Short-chain branching upto hexyl in low-density polyethylenes (LDPE) has been studied by
pyrolysis-hydrogenation fused-silica capillary gas chromatography. The branch content was …

Low‐density polyethylenes, prepared by free radical processes in high‐pressure reactors,
are dendritic polymers with complex microstructures. Both long‐and short‐chain aliphatic …

A detailed analysis was carried out on the catalytic degradation of polypropylene with silica–
alumina, using a glass tube reactor (25φ× 150 mm) at 180 to 300° C and a N 2 flow rate of …

The thermodegradation of several ethylene–α-olefin copolymers, where α-olefin was butene-
1, hexene-1, octene-1 or 4-methyl-1-pentene, was investigated by the pyrolysis-gas …
